 | | Phithirus pubis is the human pubic louse or crab louse and infests the pubic and armpit areas, although it may be found in other parts of the body with course hair. | | | MoonDragon's Obgyn Information & Discussion - Description of Human Body Lice | | | In addition to the problems caused directly by their feeding, body lice are involved in the transmission of a number of human pathogens, the most important of which are epidemic relapsing fever, caused by a spirochaete, Borrelia recurrentis; epidemic typhus, caused by a rickeesia, Rickettsia prowazekii; and murine typhus fever, caused by Rickettsia typhi. |

| | Body Louse |
| | The human louse occurs in two forms, the body louse and the head louse, and these are very similar to one another. | | | Two types of louse are adapted for living on man: the human louse, and the crab louse. | | | The head louse, which looks the same as the body louse, attaches its eggs firmly to hairs close to the scalp. |

Acinetobacter baumannii in human body louse. | | | The body louse has been demonstrated to be the vector of three human pathogens: Rickettsia prowazekii, the agent of epidemic typhus; Bartonella quintana, the agent of trench fever; and Borrelia recurrentis, the agent of louseborne recurrent fever (1). | | | While ingesting only blood from humans, the louse has a sterile midgut, and the presence of bacteria is likely caused by the louse's ingesting contaminated blood (2). |

| | Urban IPM: Insects: Lice |
| | The body louse, once the most common human louse, is now very rare in the United States, as it requires unsanitary conditions in which to reside. | | | The head louse and the body louse are closely related though their behavior is quite different, the head louse, as its name suggests, remains on the head of a person its entire life, whilst the body louse spends most time in the seams of unwashed clothing and returns to the body only to feed. | | | Body lice and head lice are subspecies of Pediculus humanus, and are very similar in appearance.One theory suggests that body lice may have evolved from head lice after man began wearing clothes. |

| | Head Lice - Daycare.com |
| | The head louse found on humans is a human parasite only, and cannot be contracted from the family dog, cat, or any other animal. | | | Whereas the head louse lives on the head and lays its eggs on the hair shaft, the body louse lays its eggs in clothing that is worn for many days without being washed, while obtaining blood meals from the person wearing the clothing. | | | Instead, since they are obligate human parasites, they have evolved with the instinct to stay on the human at all costs. |
